  1. Asynchronous allow us to run multiple task at the same time even when we have a long running program rather than having to wait until that task has finished. Once it's finished the program will present the results

  2. promise is an object which help in the representation of the eventual completion or failure of an "asynchronous " operation.
    3)like the name implies, it means the guarantee of getting a return from the function. there are three states which are pending, fulfilled, rejected.
    4)Because it waits for a promise and get its value
    5)the error is being logged to console when writing code for Node.js, it's common that modules you include in your project may have unhandled rejected promises, logged to the console by the Node.js runtime. 

  3. Async/Await is used to work with promises in asynchronous functions. It is basically syntactic sugar for promises. It is just a wrapper to restyle code and make promises easier to read and use
